Could have been negative Trump stickers. Too hard to read details from pictures I’ve seen.
Looks pro Trump aand everything looks very new. This guy was designed to make a big splash and get caught. Could be a nut but a nut but a nut with motives. This guy for sure will tell them he’s pro Trump.
The pro-Trump stickers would be in keeping with a Leftist design to smear Trump supporters.
It would be interesting to find out from neighborhood observers when the stickers were placed on the van.
